I came here with my wife for our honeymoon, and overall had a great stay! For all the recent posters in the thread, yes this is not the Ritz or Four Seasons (just look at the price!!), but that doesn't mean it is trashy.
Pre-Arrival:
I contacted the hotel about arranging for something in the room and let them know it was our honeymoon. The GM of a property I frequent had also contacted them on my behalf. I put in a SNA request for a junior suite, and it cleared 4 days prior to arrival, despite all suites being sold out when I checked online.
Check-In:
We pulled up and were immediately greeted by a cheery bellman who presented us with a lei and pulled our car to the side. He said he will unload the car after we are checked in and find out our room. The front desk only had one person working at the moment so there was a short wait, but she was apologetic and did her best to move people along quickly. She was a bit flustered though, and kept forgetting during the process the things she needed to give us, if I was platinum, and if we were celebrating a special occasion (ie she immediately congratulated us on our wedding, then 2 minutes later asked if it was a special occasion

). We chose breakfast for the amenity, were given official DYKWIA spg platinum wristbands, along with a "special occasion" champagne coupon since it was our honeymoon. I found it a bit chintzy that they had designated special occasion cards, but I guess with the number of honeymooners in Hawaii they have to do that. She mentioned we were upgraded to a suite, but that was about it, so I assumed we still had a jr suite. We went back to the bellman, who said parking by our room would be easiest and suggested we get back in the car and follow him in his golf-cart. This turned out to be extremely helpful, as it was a bit confusing to get to our building. We pulled up right in front of building 5 and he unloaded the bags for us, then went to an overlook to describe all the different places in the hotel. He also went through a map of the island, suggested activities and probably spent 30 minutes walking us through everything. Normally I would get annoyed by this as i just want to drop my stuff and go explore, but he was extremely helpful and had good advice.
The Room:
It turns out we received a very nice upgrade to one of the five suites in building 5, sitting directly on top of black rock. This building only has 10 rooms, which each suite connected to a standard room, and seemed to have the biggest suites in the hotel. From what I could tell, one suite + the presidential suite faced south toward the resort, one faced west toward the ocean, and two faced north toward the beach/resort area that direction. We had the latter that faced north, but you could still easily see the ocean and for a reservation on points getting the worst view of the best 5 room is not too shabby. The room itself was setup as a long rectangle with a hallway going down one side to a living room at the far end, a bedroom in the middle, and a half bath closest to the entrance. In the bedroom there were double doors opening to a large master bath, with a separate "throne room". This room was actually perfect for couples, as the divider between the master bedroom and living room was more of a half wall with a partition at the top which could be opened, allowing you to see straight through from the bathroom, bedroom, or living room out to the ocean. There was also a fairly large patio with 2 beach loungers and a table. While the layout of the room was amazing, the furnishings were relatively basic and definitely not luxurious. Everything was clean and in good shape though. The only thing that really bugged me was that the TVs were too old to have HDMI inputs so I could not plug in my tablet to watch movies, which would have been nice for a week long stay. They were LCDs flat screens though.
Resort:
The resort itself was very spread out which gave it more of a private / quiet feel. The restaurants were packed at times, so I think the resort was relatively full, but instead of one large pool or chair area, the pool was narrow and winded around the property, with separate smaller beach chair areas at various spots. There are two bars in the pool area so getting drinks was not too hard. They are strict with IDs though, and I was refused drinks more then once when I left my ID in my room, so make sure you keep it with you. I guess I am too used to Caribbean resorts where drinking age is not much of an issue. I think they charged for chairs on the beach.. but the pool areas were so close to the beach, we didn't see a reason to get a chair on the beach itself. Finding chairs was generally not much of a problem, and many were even shaded.
Compared to the Westin, the grounds at the Westin were MUCH nicer with waterfalls, flamingos, rocks etc. However it was more compacted and seemed to have a lot more people running around every time we were there. I also don't think you could sit as close to the beach. The Sheraton was "simpler" but not necessarily in a bad way.
Service:
While the service from the front desk, bellman and concierge was EXCELLENT, the rest of staff was a bit lacking. Instead of towel cards redeemable for one towel at a time, we were provided DYKWIA SPG Plat wristbands good for unlimited towels. I guess that is a nice token gesture the hotel can use to recognize Plats without costing much revenue, but did seem a little silly. We were told it was so the hotel staff could recognize us and provide better service, but I really do not think that happened. One day we returned to the resort late in the afternoon and wanted to spend the few hours left in the day relaxing by the pool. The pool area was relatively crowded since everyone had been camped out all day but we eventually found a spot, and place an order for some drinks and food to be brought to us. After we settle in, a staff member comes by and informs then he has to clear this area to set up for a wedding in 30 minutes, so we will have to vacate then. He did not offer to help us find an alternative spot, or help us carry all the drinks/food that are now sitting on the table next to us, and they had not put up a sign to warn us that the area would be closing. After 15 minutes I did find some nearby chairs in a different area open up, but had to make several trips back and forth to carry everything. I completely understand that they have some areas reserved for weddings and need to clear chairs in the late afternoon, but I would expect them to help relocate us.
Breakfast:
The plat breakfast amenity was good for a continental breakfast, or you could upgrade to the buffet with made to order omelettes for $10. We did the Continental breakfast one day, and it was actually very filling with a tasty yogurt parfait and several varieties of pastries and fruit. The breakfast was great, and we though $10 for the buffet was reasonable but service was HORRIBLE. There were wait staff everywhere, and almost everyone did buffet, so you would think they could serve us efficiently but that was not the case. It would often take 10-20 minutes and several reminders to get drinks, ketchup, etc. Once we did get our drinks they generally would not return. Also sometimes they would only offer us orange juice, while tables nearby would be offered other types of juices. The same waiting game would happen when we asked for the check. Also, when it wasn't busy they would leave tables sitting full of food and just let the birds have it at it instead of clearing it. I tried playing the game of tipping big the first day or two in the hopes they would remember us and provide better service the next day, but even that did not help. I don't think we received decent service for even one of six days we ate there, and for a buffet you really don't expect much. For the $10 we kept doing it due the convenience, but there is no way I would pay full price to sit there waiting for everything I needed.
Food:
The cliff dive bar had some decent options for snacks/light dinner that were not horribly overpriced so we at there several times. In particular it was nice to sit there in evenings to watch the sunset and they would usually have someone playing guitar. We did not eat at Black Rock due to the service received there during breakfast, as I assume it is the same wait staff. We did got to Tappenyaki one day and it was enjoyable, but definitely not anything amazing and a bit overpriced. Hula Grill in Whaler's village is right off the beach and was a great option for lunch. The food was better then what we ate at the Sheraton for a lower price.
Spa:
I would recommend doing massages inside the spa instead of at the bungalow near the beach. They have these private outdoor rooms which are open at the top so you can hear the ocean and feel the breeze, but be in complete privacy. Like the rest of the hotel, the spa was not fancy but definitely very relaxing and enjoyable. The pricing here was a bit weird. We booked through the concierge, who gave us $20 off coupons, but the price when booked through the concierge was more then if you booked at the spa desk (and yes.. both are owned/run by the hotel). In the end it was cheaper using the concierge + coupons, but very odd with the different pricing situations. It seems you need to call both the spa directly and the concierge before making an appointment if you want to make sure you pay the best price.
Overall it was a great stay. If I return I might try the Westin due to their nicer pool area, but I think the Sheraton is probably a more relaxing property.
